"He divined early the value of being sluggish, lax, drowsy..." I needn't worry about my own bouts of sluggishness! As an aware, daydreaming child, sitting under a beechnut tree, Hampl, too, committed early to "the life of the mind," her italics.
Revising my own previous worries, as someone who, like Hampl, later in life, makes relentless to-do lists, I can concur in regard to late-stage laid-backness: "This isn't sloth, it isn't laziness. It isn't even exhaustion. It is a late-arriving awareness of consciousness existing for its own purpose, rippling with contentment and curiosity. One's own idiosyncrasy reveals itself as a pleasure, without other value--but golden, amusing, integrity hard-won and now at its leisure. Hand on heart, this life of the mind, lolling--tending to life's real business."
Oddly, Montaigne doesn't look all that gay and free in his frilly ruff!
